This paper presents laser-based, three-dimensional (3D) measuring applications involving three different bodies in motion: a knee joint during leg motion (1) , thoraco - abdominal and back deformation during breathing (2) and the shape of a foot during walking (3) . The first (1) setup is based on a commercial sensor Kinect, whereas the second (2) and the third (3) are based on custom - developed, multiple - line, triangulation measuring systems. Special attention was given to the color - modulation principle and the selection of the proper optical components. Based on the calibration, the accuracy of the system is 1.4 mm (1), 0.7 mm (2) and 0.5 mm (3 ), while the measuring range is 900 x 700 x 600 mm (1), 400 x 600 x 500 mm (2) and 400 x 160 x 180 mm (3). The camera frame rate for each setup is 30 Hz (1), 25 Hz (2) and 30 Hz (3). All the systems were evaluated in vivo on adult volunteers. The presented measuring systems are capable of real - time measurements , while enabling a precise and nonintrusive analysis of shape deformation, which has a lot of potential in clinical diagnosis, patient assistance or the development of new shoe models.
